Irish bagpipes, violin, drum, HMV IM372. Two of this charming trio's recordings were reissued on the Classics of Irish Piping LP/CD. According to Sean Reid (who wrote the reissue's liner notes) it was an impromptu recording of Leo and two studio musicians who weren't players of Irish music, but read off charts Leo wrote out on the spot. These three reels have long been favorites of musicians and pipers especially; Bonnie Kate was recorded on cylinder by Patsy Touhey, the Blackberry Blossom by Michael Carney (also on cylinder). Miss Monaghan was a great favorite of Seamus Ennis, and many recordings of him playing his extremely intricate setting exist; some have even lauded an early 50s recording of it as his greatest moment on disc. Leo included the tune in his 1936 Tutor (included in the Leo Rowsome Collection) and while it isn't the maze of notes Seamus played it is a lovely setting, contrasting from the standard version played nowadays.
More of Leo's 78 RPM recordings may be heard on the CD "Classics of Irish Piping" on the Topic label. Leo's 50s LP Ri Na Bpiobairi (The King Of The Pipers) has also been reissued on CD. Walton's has published an excellent book of Leo's transcriptions, the Leo Rowsome Collection of Irish Music.
